To attain miniaturization in a configuration in which wheels are offset relative to a pivot axis.SOLUTION: A drive wheel 110 is arranged such that a rotational axial core O5 of wheels, which intersects with an axial core O2 of an axle 37 and runs vertically, is shifted horizontally perpendicular to the axial core O2 of the axle 37 relative to an axial core O1 of a pivot shaft 35, and an axial core O3 of a first output shaft 40A for transmitting the rotation of a first input shaft 25A to the axle 37 and an axial core O4 of the second output shaft 40B for transmitting the rotation of a second input shaft 25B to the axle 37 are inclined relative to the axial core O1 of the first input shaft 25A and the axial core O1 of the second input shaft 25B when viewed in an axial direction of the axle 37.SELECTED DRAWING: Figure 4
【課題】旋回軸に対して車輪をオフセットした形態において、小型化を図ること。【解決手段】駆動輪110は、車軸37の軸心O2に交差して鉛直方向に沿う車輪の回転軸心O5が、旋回軸35の軸心O1に対して車軸37の軸心O2に直交する水平方向にずれて配置され、第一入力軸25Aの回転を車軸37に伝達するための第一出力軸40Aの軸心O3、及び第二入力軸25Bの回転を車軸37に伝達するための第二出力軸40Bの軸心O4が、車軸37の軸線方向で見た場合に、第一入力軸25A及び第二入力軸25Bの軸心O1に対して傾斜して設けられる。【選択図】図4
